If you’re in a happy marriage, you’ll end up looking like your partner.

Don’t laugh – it’s been found in a study that couples who live happily together end up resembling each other.

It’s because people in a cordial relationship tend to unconsciously copy each other’s facial expressions. As parallel sets of muscles are strengthened in unison, this gradually molds similar lines, wrinkles and ridges, making the two faces appear more alike.

The study found that the greater the facial similarity, the happier the couples reported being in their marriages.

Now I want to know if they’ve done studies on dogs and dog owners who look alike… and why!
